ter, count of Worcester, and State of Massachusetts, ave invented an Improvement in Thread-Boards for Spinning Frames, of

which the following description, in connec tion with the accompanyin drawings, is a specification, like letters on, t e drawings representing like parts.

This invention relates to the thread-board and twisting machines wherein it of spinnin Fthat the thread-guide holders may for dofling and other purposes. The object of the invention is to provide a simple, strong, and efficient construction of parts with provision foradjustment and so arranged thatthe thread-guide holders will not be tipped out of place accidentally. I

The nature of the invention will more fully ap ear from the following description and be set forth more particularly in the ap- The drawin s represent a section of a thread-board s owing a section of the apparatus which will be of a length to correspond with the spinning or twisting machine.

Figure 1 is a top lan view of a portion of the roller-beam w1t a portion of t e devices for makin thereto. ig. 2 represents a front elevation, with the thread-guide holders and liftin bar elevated, of a'section of the apparatus s own in Fig. 1; and Fig. 3 is a view in cross-section on the line a; w of Fig. 1. section on line y, Fig. l. The usual ro ler-beam and spinning-frame is represented at A. In front of this beam and attached thereto in any suitable man ner, as by bolts C, are a series of bearings D,

Fig. 4 is a crosswhich should be suflicient in number to support the parts on the apparatus. As shown, there is one bearing for eve four threadguide holders; but under or inary circumstances the proportion may be greater. A rod E is mounted in the bearings D and extends the entire length of the roller-beam and should be so positioned as to come quite close to. the iace of the roller-beam A.

The thread-guide holders F are formed of sheet metal with downturned edges F, whereby rigidity of construction is'secured, and have mounted at the forward end the usual thread-guide eyes G, a suitable adjustthe present invention applied ment for the thread- 'uide eyes in the holders v being provided and erein shown as consist- 111g ofa channeled guard-plate g, fitting over the bent end g of the guide-e e and clamp in the guide-eye in position y means of a bolt g The rear end of each thread-guide holder is provided with a plurality (here shown as two) of hinged loops H, which may be formed from the metal of the thread-guide holder or on an independent hin ed piecebolted thereto, as at h. hese hinge loops fit over the rod E, whereby each thread-guide holder 18 independently journaled upon the same axis. A lifting-bar K is mounted beneath the thread-guide holders and parallel with the rod.. Preferably it is mounted by direct connection to the rod, and for this purpose a series of yokes' L are provided, one for each thread-guide holder, except where the bean ings D are located. These okes are clamped to the lifting-bar in a suite le manner, as by a-bolt L The bearings D and the yokes L are located, respectively, between the hinged 100 s H of the thread-guide holders, so that t e thread-guide holders are held in definite position longitudinally of the roller-beam.

An adjustment is provided whereby the thread-guide holders may be positioned properly with respect to the spindle or other de- I vice, and this consists of slotting the bearings D where they are bolted to the roller-beam, so that they can be moved longitudinally of the roller-beam, and also slottin the yokes L where they are bolted to the li ting-bar K, where they may be moved laterally of the lifting-bar. In this manner each threadguide holder may be adjusted to the desired almplunt, which in all cases is comparatively s i t.

i stop D is provided on each bearing D, which limits the downward motion of the liftin bar K. Hence the lifting-bar Kserves to he (1 the thread-guide holders in their normal operative osition.

It will t us be seen that in operation any thread-guide holder may be tipped u independently" of the other on the rod and when it is desired to lift the entire series all that is necessary is to raise the lifting-bar K,

.for which purpose a simple lever or handle K is provided, and thereupon the entire se- 1, In a machine of the character described, bearings adapted to be attached to the rollerbeam, a rod sustained in said bearings, a series of thread guide holders hin ed on said rod, a lifting-bar mounted beneath said holders and parallel with said rod, whereby individual holders may be swung u ward on said rod, and the entire series may e swung up- Ward on said rod by raising said lifting-bar.

2. In a machine of the character described, bearings adapted to be attached to the rollerbeam, a rod sustained in said bearings, a series of threadguide holders hin ed on said rod, a lifting-bar beneath said elders and fulcrumed on said rod whereby individual holders may be swung upward on said rod, and the entire series may be swung upward on said rod by raising said lifting bar.

3. In a machine of the character described, bearings adapted to be attached to the roller-- beam, a rod sustained in said bearings, a se ries of thread-guide holders hin ed on said rod, a lifting-bar mounted beneat said holders and parallel with said rod, whereby individual holders may be swung upward on said rod, and the entire series may besw'ung up- Ward on said rod by raising said lifting-bar, a stop to limit the downward movement of said lifting-bar, causing the lifting-bar to main tain the holders in operative position.

4. In a machine of the character described, bearings adapted to be mounted on the rollerbeam, a rod sustained in said bearings, a series of thread-guide holders, each presenting ably mounted on the roller-beam, a rod sus tained in said bearings, a series of threadguide holders, each presenting separated hinged loops embracing said rod,.a liftingbar, a series of yokes mounted andlongitudk nally adjustable on said lifting-bar and embracing said rod between said hingedloops, a

stop to limit the downward movement of said liftin -bar.

6. in a machine of the character described, a series of bearings adapted to be adj ustably mounted on the roller-beam, a rod sustained in said bearings, alifting-bar having a series of yokes adjustably mounted on and embracing said rod, a series of thread-guide holders, each provided with two separated hinged loops embracing said rod and adapted to span one of the said hearings or one oi the said yokes,a stop to limit the downward swinging movement of said lifting-bar.
